C# 8 and beyond

With C# being the most dynamic language in the market, it is constantly improving. With the newer features, such as nullable reference types, async streams, ranges and indices, interface members, and many other features that came with the latest version of C#, they have enhanced the basic features and helped programmers to take advantage of these new constructs, hence making their lives easier.

Note that, during the language's evolution, the .NET framework was also made open source. You can find the source code of the .NET framework at the following link: https://referencesource.microsoft.com/.
